Energy level — A quantum mechanical system or particle that is bound that is, confined spatially can only take on certain discrete values of energy. This contrasts with classical particles, which can have any energy. These discrete values are called energy… … Wikipedia

Rotational energy — The rotational energy or angular kinetic energy is the kinetic energy due to the rotation of an object and is part of its total kinetic energy. Looking at rotational energy separately in an object s centre of mass frame, one gets the following… … Wikipedia
Kinetic energy — The kinetic energy of an object is the extra energy which it possesses due to its motion. It is defined as the work needed to accelerate a body of a given mass from rest to its current velocity . Having gained this energy during its acceleration … Wikipedia
Internal energy — In thermodynamics, the internal energy of a thermodynamic system, or a body with well defined boundaries, denoted by U , or sometimes E , is the total of the kinetic energy due to the motion of molecules (translational, rotational, vibrational)… … Wikipedia
kinetic energy — Physics. the energy of a body or a system with respect to the motion of the body or of the particles in the system. Cf. potential energy. [1865 70] * * * Form of energy that an object has by reason of its motion. The kind of motion may be… … Universalium
Outline of energy — See also: Index of energy articles In physics, energy (from the Greek ἐνέργεια – energeia, activity, operation , from ἐνεργός – energos, active, working [1]) is a scalar physical quantity that describes the amount of work that can be performed by … Wikipedia
List of energy topics — This is a list of energy topics which identifies articles and categories that relate to energy in general. Energy refers to the ability to do work . The word is used in several different contexts. The engineering use has a precise, well defined… … Wikipedia
Entropy (energy dispersal) — The thermodynamic concept of entropy can be described qualitatively as a measure of energy dispersal (energy distribution) at a specific temperature. Changes in entropy can be quantitatively related to the distribution or the spreading out of the … Wikipedia
